The tracks and city information is fetched from the SoundCloud API–in fact the list of cities and tracks is even updated in real time as new tracks roll into SoundCloud. Additionally, pictures for each city are fetched from Flickr.

Try listening to Tunapuna, Trinidad for danceable tropical rhythms or to Belgrade for some of that eastern Europe progressive. It’s surprising how distinctive cities sound around the world!

We should also mention that Citysounds.fm is built with Ruby on Rails using our excellent Ruby Gem. The gem makes it a breeze to integrate SoundCloud into your application. You can read more about it over at Github.
